一种医学图像几何特征的自动检测

A Method for Automatic Detection of Geometric Features of Medical Images

医学图像配准的方法有许多种 ,它的原理都是选取合适的图像特征量 ,根据特征量再来确定配准变换 ,因此特征量的选取是图像配准的第一步。目前用于配准的图像特征量有多种 ,如图像边界、图像外标记点等。本文提供了一种提取图像脊特征 ,作为用于配准的特征量的方法 。

There are many methods for medical image registration. The principle of them is to extract appropriate image features, and to decide which registration transformation to be used according to features selected. So the extraction of image features is the most important step for image registration. There are many kinds of image features to be used for registration, such as image edges, marks outside of image, etc. In this paper is presented a method to extract the image ridge feature for image registration, and good results were obtained.
